Distillation device for producing high-purity germanium tetrachloride

Abstract

The invention discloses a distillation device for producing high-purity germanium tetrachloride. The distillation device includes a distillation tank and a condensation tank. A material inlet and a first gas inlet are arranged on one side of the distillation tank and a second gas inlet is arranged on the other side of the distillation tank; a gas outlet is arranged on the top of the distillation tank; a spiral shaft is vertically disposed in the axial center in the distillation tank and is provided with a plurality of infrared heating blocks which are uniformly arranged spirally on the external wall of the spiral shaft in the vertical direction; an infrared heating jacket is disposed on the bottom of the distillation tank; a temperature detector is disposed in the infrared heating jacket; the top of the distillation tank is connected to the condensation tank through a first gas outlet pipe; a spiral condensing pipe is arranged in the condensation tank; a second gas outlet pipe and a third gas outlet pipe are arranged on the condensation tank, wherein the second gas outlet pipe is connected to the second gas inlet. The distillation device is high in heating speed and has good temperature control effects.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a distillation device for producing high-purity germanium tetrachloride. Background technique [0002] At present, in chemical production, when encountering a large amount of liquid phase separation, it is often necessary to use a distillation tower for separation and purification. However, most of the distillation towers currently used use alcohol or kerosene or coal to burn heat to provide heat. In this way, combustion heating consumes a lot of fuel, and different raw materials must use different fuels, otherwise it is easy to damage the raw materials, and the exhaust gas emitted after fuel combustion will also pollute the environment. At the same time, the staff must keep an eye on the temperature of each part of the distillation tower, and it is very difficult to control the temperature. Therefore, it is necessary to improve the existing distillation tower so that it ...
